Chaining the sequence of events through awareness of their temporal relations is an important aspect of text understanding. As a rule, text provides only partial knowledge of event unfolding however various types of additional sources (documents, personal diaries, etc.) provide an added knowledge to make chronology more precise. The paper argues the novel approach to automated retrieval of info...

Usually, the material for learning is given in a positive form, i.e. xxx is yyy. This type of information will help organize the core of the target knowledge. Instead of this type of information, negative information, i.e. xxx is not zzz, will help sharpen the edge or extent of the target knowledge. Hence, it is expected that the negative information will have an effect of minimizing the chance...

This chapter presents a thorough review of current practice in eliciting, representing and amalgamating knowledge from multiple experts, with a focus on the use of graphical representations to support the process. The important points of the discussion are illustrated by presenting a specific methodology for eliciting and combining knowledge from multiple experts. This methodology provides a st...

Most large systems development efforts proceed in a top-down fashion where initial specifications and requirements are incorporated into a high-level design, followed by programs based on this design. However, a major part of the software life-cycle effort is devoted to maintenance. While several existing methodologies aid in the initial phases of requirements and specification, they have prove...

The value of a software engineering experience repository like for any other experience-based information systems tends to degrade with time. To keep the value of such a system, evaluation and maintenance is an essential. While evaluation monitors the "value" over time, maintenance has to preserve or improve this "value". Evaluation and maintenance should not simply happen ad-hoc but systematic...

The paper focuses on the description of the approach, taken within the ESPRIT BRA project ACQUILEX, towards: i) acquisition of semantic information from several machinereadable dictionaries (in four languages), and ii) its representation in a common Lexical Knowledge Base. Knowledge extraction is guided by a) empirical observations and b) theoretical hypotheses. As for representation, we stress...

In this paper, a framework for acquiring common sense knowledge from the Web is presented. Common sense knowledge includes information about the world that humans use in their everyday lives. To acquire this knowledge, relationships between nouns are retrieved by using search phrases with automatically filled constituents. Through empirical analysis of the acquired nouns over WordNet, probabili...

The last decade has seen a burgeoning of reports associating brain structure with specific skills and traits (e.g., [1-8]). Although these cross-sectional studies are informative, cause and effect are impossible to establish without longitudinal investigation of the same individuals before and after an intervention. Several longitudinal studies have been conducted (e.g., [9-18]); some involved ...

We describe some initial experiences in dealing with the task of acquiring knowledge where a very large collection of case histories is available. A Knowledge Discovery in Databases (KDD) approach is taken. KDD is the process of extracting novel information and knowledge from large databases, consisting of many interacting stages performing specific data manipulation and transformation operatio...
